其实并不是所有485转换器都能够带128台设备的，要根据485转换器内芯片的型号和485设备芯片的型号来判断，只能按照指标较低的芯片来确定其负载能力。一般485芯片负载能力有三个级别――32台、128台和256台。。此外理论上的标称往往实际上是达不到的，通讯距离越长、波特率越高、线径越细、线材质量越差、转换器品质越差、转换器电能供应不足(无源转换器)、防雷保护越强，这些都会降低真实负载数量。

   3、485总线是一种最简单、最稳定、最成熟的工业总线结构

   这种概念是错误的。485总线是一种用于设备联网的、经济型的、传统的工业总线方式。。其通讯质量需要根据施工经验进行调试和测试采可以得到保证。485总线虽然简单，但也必须严格按照安装施工规范进行布线。

   二、必须严格按照施工规范施工

   在485总线系统施工时必须严格按照施工规范施工，特别应注意下面几点。

   1、485+和485－数据线一定要互为双绞。

   2、布线一定要布多股屏蔽双绞线。多股是为了备用，屏蔽是为了便于出现特殊情况时调试，双绞是因为485通讯采用差模通讯原理，双绞的抗干扰性较好。不采用双绞线是错误的。

   3、485总线一定要用手牵手式的总线结构，坚决避免星型连接和分叉连接。

   4、设备供电的交流电及机箱一定要真实接地，而且接地良好。有很多地方表面上有三角插座，其实根本没有接地，接地良好可以防止设备被雷击、浪涌冲击。静电累积时可以配合设备的防雷设计较好地释放能量，保护485总线设备和相关芯片不受伤害。
